Description

Technical Field

[0001] This utility model relates to the field of container assembly technology, and in particular to a heavy truck container connector. Background Technology

[0002] Heavy-duty truck container connectors are specialized devices used to securely fasten containers to heavy-duty trucks, such as twist locks or fasteners. Their function is to ensure a stable connection of containers during transportation, preventing slippage or detachment, thereby ensuring cargo safety and road traffic efficiency. They are mainly used in logistics transportation, port loading and unloading, road freight, and container multimodal transport.

[0003] When existing heavy-duty truck container connectors are in operation, due to prolonged irregular vibration and rigid contact with the container corner fittings, wear may occur between the locking pin and the rotating threaded sleeve, causing loosening. This can result in the top of the locking pin jumping, making it unable to effectively lock the container corner fittings, causing the container to sway and become unstable, thus increasing safety hazards. Utility Model Content

[0004] This utility model discloses a heavy-duty truck container connector, which aims to solve the technical problem that the heavy-duty truck container connector becomes loose due to vibration and wear, resulting in the failure of the locking function, causing the container to shake and posing a safety hazard.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A heavy-duty truck container connector includes a container body. A shearing block is fixedly connected to the upper side of the container body. A container corner piece is placed on the upper side of the container body. A locking pin is slidably connected inside the shearing block. Two detection components are equally spaced on the upper inner wall of the locking pin. A rotating threaded sleeve is threaded onto the outer wall of the locking pin. The rotating threaded sleeve slides inside the lower end of the container body. Multiple rotating handles are fixedly connected at equal intervals to the outer wall of the rotating threaded sleeve. A handle glove is provided on the lower outer wall of the locking pin. The handle glove and the locking pin are fixedly connected by bolts. Emergency stabilizing components are provided on both sides of the container body. Each emergency stabilizing component includes a fixing block. Two fixing blocks are fixedly connected at equal intervals to one side of the container body. The interiors of the two fixing blocks are connected to the same rotating shaft through bearings. A stabilizing handle is fixedly connected to the outer wall of the rotating shaft. A stabilizing slot plate is connected to the opening of the stabilizing handle through bearings.

[0006] In a preferred embodiment, multiple compression springs are arranged at equal intervals inside the groove of the stabilizing groove plate. One end of two compression springs located at the same end is fixedly connected to the same compression plate. The two compression plates slide inside the stabilizing groove plate respectively, and the same corresponding rotating handle is clamped between the two compression plates.

[0007] In a preferred embodiment, a ratchet ring is fixedly connected to the outer wall of one end of the rotating shaft, and a grooved cylinder is fixedly connected to the outer wall of a fixing block near the ratchet ring, with the ratchet ring located inside the grooved cylinder.

[0008] In a preferred embodiment, a sliding ring is slidably connected inside the grooving cylinder, and a ratchet groove sleeve is fixedly connected inside the sliding ring, with the ratchet groove sleeve engaging with the ratchet ring.

[0009] In a preferred embodiment, one end of a return spring is fixedly connected to one side of the sliding ring, and the other end of the return spring is fixedly connected to a corresponding fixed block.

[0010] In a preferred embodiment, the detection component includes a sliding block, two sliding blocks located on the same side of the inner wall of the upper end of the locking pin are slidably connected to the same contact plate on opposite sides, multiple sliding blocks are fixedly connected to the inner wall of the upper end of the locking pin at equal intervals, an extrusion head is fixedly connected to the upper side of the contact plate, and the lower side of the contact plate is in extrusion contact with the inner wall of the lower end of the container corner fitting.

[0011] In a preferred embodiment, the upper inner wall of the locking pin is provided with a setting groove, and a pressure sensor is provided inside the setting groove. The force-receiving end of the pressure sensor is located directly above the extrusion head. An alarm is provided at the upper end of the locking pin. Two pressure springs are fixedly connected at equal intervals to one end inside the setting groove of the locking pin, and the other ends of the two pressure springs are fixedly connected to the contact plate.

[0012] As can be seen from the above, the heavy-duty truck container connector provided by this utility model has the ability to detect loosening caused by wear between the locking pin and the rotating threaded sleeve in a timely manner through pressure sensor and pressure fluctuation changes of the extrusion head, and trigger an alarm to notify the staff to stop work and check. This avoids the risk of increased safety hazards due to unstable container shaking. At the same time, when it is necessary to continue working for a period of time, the rotating handle can be rotated downward to make the stabilizing slot plate press the rotating handle downward, so that the rotating handle drives the locking pin downward through the rotating threaded sleeve, thereby re-fixing the container corner piece. This can meet the emergency needs in specific situations and greatly improve work efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] The heavy-duty truck container connector disclosed in this utility model is mainly used in scenarios where the heavy-duty truck container connector becomes loose due to vibration and wear, resulting in the failure of the locking function, causing the container to shake and posing a safety hazard.

[0020] Reference Figures 1-4 A heavy-duty truck container connector includes a container body 2. A shearing block 6 is fixedly connected to the upper side of the container body 2. A container corner piece 1 is placed on the upper side of the container body 2. A locking pin 7 is slidably connected inside the shearing block 6. Two detection components 8 are equally spaced on the upper inner wall of the locking pin 7. A rotating threaded sleeve 9 is threaded on the outer wall of the locking pin 7. The rotating threaded sleeve 9 slides inside the lower end of the container body 2. Multiple rotating handles 3 are fixedly connected at equal intervals on the outer wall of the rotating threaded sleeve 9. A handle glove 4 is provided on the lower outer wall of the locking pin 7. The handle glove 4 and the locking pin 7 are fixedly connected by bolts. Emergency stabilizing components 5 are respectively provided on both sides of the container body 2. The emergency stabilizing components 5 include fixing blocks 506. Two fixing blocks 506 are fixedly connected at equal intervals to one side of the container body 2. The interior of the two fixing blocks 506 is connected to the same rotating shaft 502 through bearings. A stabilizing handle 501 is fixedly connected to the outer wall of the rotating shaft 502. A stabilizing slot plate 503 is connected to the opening of the stabilizing handle 501 through bearings.

[0021] In this scheme, multiple compression springs 505 are equally spaced and arranged inside the groove of the stabilizing groove plate 503. One end of two compression springs 505 located at the same end is fixedly connected to the same compression plate 504. The two compression plates 504 slide inside the stabilizing groove plate 503 respectively, and the same corresponding rotating handle 3 is clamped between the two compression plates 504.

[0022] In this scheme, a ratchet ring 511 is fixedly connected to the outer wall of one end of the rotating shaft 502, and a sliding cylinder 509 is fixedly connected to the outer wall of a fixing block 506 near the ratchet ring 511, with the ratchet ring 511 located inside the sliding cylinder 509.

[0023] In this design, a sliding ring 510 is slidably connected inside the sliding cylinder 509, and a ratchet sleeve 507 is fixedly connected inside the sliding ring 510. The ratchet sleeve 507 is engaged with the ratchet ring 511.

[0024] In this design, one end of a return spring 508 is fixedly connected to one side of the sliding ring 510, and the other end of the return spring 508 is fixedly connected to the corresponding fixing block 506.

[0025] When securing the container, the ratchet sleeve 507 is pulled open to overcome the action of the return spring 508 and disengage from the ratchet ring 511, thereby releasing the lock on the stabilizing handle 501. Then, the stabilizing slot plate 503 is placed on the outer wall of the corresponding rotating handle 3. At this time, the upper and lower ends of the rotating handle 3 are in contact with the corresponding pressing plate 504 respectively. Then, the stabilizing handle 501 is rotated upward, thereby moving the stabilizing slot plate 503 upward and lifting the corresponding rotating handle 3. During this process, since the rotating handle 3 is inside the stabilizing slot plate 503, the rotating handle 3 is prevented from rotating due to vibration, ensuring that the locking pin 7 does not jump during operation. Then, the ratchet sleeve 507 is released and re-engaged with the ratchet ring 511 under the action of the return spring 508, so that the rotating handle 3 is locked again, ensuring the stable limit of the rotating handle. When the locking pin 7 and the rotating threaded sleeve 9 become loose due to wear after prolonged irregular vibration and rigid contact with the container corner fitting 1, the rotating handle 3 is rotated downwards to cause the stabilizing slot plate 503 to press the rotating handle 3 downwards. This causes the rotating handle 3 to move the locking pin 7 downwards through the rotating threaded sleeve 9, thereby re-fixing the container corner fitting 1. This can meet the emergency needs in specific situations and greatly improve work efficiency.

[0026] Reference Figure 1 , Figure 2 and Figure 4In a preferred embodiment, the detection component 8 includes a slide block 801. Two slide blocks 801 located on the same side of the upper inner wall of the locking pin 7 are slidably connected to the same contact plate 802 on opposite sides. Multiple slide blocks 801 are fixedly connected to the upper inner wall of the locking pin 7 at equal intervals. An extrusion head 806 is fixedly connected to the upper side of the contact plate 802. The lower side of the contact plate 802 is in extrusion contact with the lower inner wall of the container corner piece 1.

[0027] In this design, a setting groove is provided on the upper inner wall of the locking pin 7, and a pressure sensor 804 is installed inside the setting groove. The force-receiving end of the pressure sensor 804 is located directly above the extrusion head 806. An alarm 803 is installed on the upper end of the locking pin 7. Two pressure springs 805 are fixedly connected at equal intervals inside the setting groove of the locking pin 7, and the other ends of the two pressure springs 805 are fixedly connected to the contact plate 802.

[0028] When the locking pin 7 and the rotating threaded sleeve 9 become loose due to wear after prolonged irregular vibration and rigid contact with the container corner fitting 1, the jumping caused by the loosening of the locking pin 7 will cause the squeezing force of the extrusion head 806 in the detection component 8 on the pressure sensor 804 to fluctuate significantly, thereby triggering the alarm 803 and notifying the staff to stop work and come to check, thus avoiding the risk of increased safety hazards due to the unstable shaking of the container.

[0029] Working principle: During use, align the container corner fittings 1 installed on the four corners of the container with the corresponding main truck container connectors on the heavy truck. Simultaneously, rotate the locking pin 7 by turning the adjusting handle on the glove 4. Then, the top of the locking pin 7 falls into the groove on the shear block 6, with the two sides of the top of the locking pin 7 positioned above the lower inner wall of the container corner fitting 1. Then, rotate the rotating threaded sleeve 9 by rotating the handle 3. Since the rotating threaded sleeve 9 is threadedly connected to the locking pin 7, the upper end of the locking pin 7 will descend as the rotating threaded sleeve 9 rotates. During this process, the two contact plates 802 overcome the pressure springs 805 and press against the lower inner wall of the container corner fitting 1, while the two pressing heads 806 press against the corresponding pressure sensor 804. The pressure sensor 804 records the pressure value. By pulling open the ratchet sleeve 507, it overcomes the action of the return spring 508 and disengages from the ratchet ring 511, thereby releasing the lock on the stabilizing handle 501. Then, the stabilizing slot plate 503 is placed on the outer wall of the corresponding rotating handle 3. At this time, the upper and lower ends of the rotating handle 3 are in contact with the corresponding pressing plate 504 respectively. Then, the stabilizing handle 501 is rotated upward, thereby moving the stabilizing slot plate 503 upward and lifting the corresponding rotating handle 3. During this process, since the rotating handle 3 is inside the stabilizing slot plate 503, the rotating handle 3 is prevented from rotating due to vibration, ensuring that the locking pin 7 will not jump during operation. Then, the ratchet sleeve 507 is released and re-engaged with the ratchet ring 511 under the action of the return spring 508, so that the rotating handle 3 is locked again, ensuring the stable limit of the rotating handle 3. When subjected to irregular vibrations and rigid contact with the container corner fitting 1 for an extended period, wear occurs between the locking pin 7 and the rotating threaded sleeve 9, causing loosening. The vibration caused by the loosening of the locking pin 7 will cause significant fluctuations in the pressure exerted by the extrusion head 806 on the pressure sensor 804 in the detection assembly 8, thereby triggering the alarm 803 and notifying the staff to stop work and inspect the area. This avoids the risk of increased safety hazards due to the unstable container shaking. When it is necessary to continue working for a period of time, the staff can rotate the rotating handle 3 downwards to cause the stabilizing slot plate 503 to press the rotating handle 3 downwards. This causes the rotating handle 3 to move the locking pin 7 downwards through the rotating threaded sleeve 9, thereby re-fixing the container corner fitting 1. This can meet the emergency needs in specific situations and greatly improve work efficiency.

[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
